Reference in the specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase “in one embodiment” in various places in the specification do not necessarily all refer to the same embodiment.

FIG. 1 is a perspective view of an exercise machine assembly according to one embodiment of the present invention. Exercise machine (or device) 100 can include seat pan 101 tiltably or movably mounted to a base assembly including seat base 105. Seat pan 101 may be shaped concaved in a certain shape to receive a user's body at a sitting position. Handle bars 103 may be detachably coupled to seat base 105. In one embodiment, seat pan 101 may be tilted against seat base 105 along the edge to provide a user recoil force or resisting force back to untilted positions. The user may hold handle bars 103 in the course of waist, abdominal or pelvic rotation exercise while tilting seat base 101 in a wavy manner.

FIGS. 2A-2B are cross sectional views of an exercise machine assembly according to one embodiment of the present invention as shown in FIG. 1. Turning now to FIG. 2A, view 200A may include seat pan 101 rotatably attached to a base assembly via a flexible structure. The base assembly may include seat base 105 housing inner base 221 which provides chamber 225 inside the base assembly to allow movement of the flexible structure. A pair of handler bars 103 may be fixedly attached to the base assembly to allow a user to use the hand holds to cause movement of seat pan 101.

The base assembly may include base protrusion 219 to secure the bottom end of the flexible structure. For example, base protrusion 219 may comprise a post or tube secured to inner base 221 via screw 223. Inner base 221 may have recesses and protrusion structures, such as inner recess 229 and outer recess 231, formed at the bottom to house the flexible structure. For example, cylindrical spring 211 and conical spring 217 may be fittingly positioned inside inner base 221 at the bottom end of the flexible structure separately via inner recess 229 and outer recess 231.

The base assembly may include ring cover 215 secured on top of inner base 221. Mounting structures between seat pan 101 and seat base 105 may be covered with side cover 213 sitting on top of ring cover 215. Side cover 213 may be made of flexible material in a tube like forms to allow tilting or other movements of seat pan 101 relative to seat base 105.

The flexible structure may include one or more resilient members situated longitudinally between a top end and a bottom end to provide elastic forces when the flexible structure is deformed. For example, the flexible structure may include cylindrical spring 211 positioned within conical spring 217. Cylindrical spring 211 may have opposite ends longitudinally between the top end and the bottom end of the flexible structure.

Various resilient forces may be provided by different resilient members in the flexible structure. For example, the flexible structure may be configured for cylindrical spring 211, which may be bendable longitudinally, to be bended to provide bending force via movement of seat pan 101. Alternatively or additionally, conical spring 217 may be compressed to provide recoil force via movement of seat pan 101. Conical spring 217 may be shaped, for example, to increase stability with less vibration.

Seat pan 101 may be movably attached to the top end of the flexible structure via a seat protrusion. For example, seat pan 101 may be affixed with seat plate 207 at the bottom side of seat pan 101. Seat plate 207 may include protruded portion 227 which may form a circular tube. Flanged bushing 209 may have a sleeve inserted with (or encompassing) cylindrical spring 211 longitudinally and a flange extended for the top end of conical spring 217 perpendicular to the longitudinal direction. The seat protrusion may comprise protruded portion 227 and/or flanged busing 209.

For example, seat pan 101 may be engaged with the flexible structure with protruded portion 227 inserted into the inner side of cylindrical spring 211. Thus, seat pan 101 may be engaged with the flexible structure with conical spring 207, flanged bushing 209, conical spring 217 and protruded portion 227 sandwiched and fittingly positioned between each other having a common longitudinal direction to allow the flexible structure to provide resilience force to support wavy (or wave like) movement of seat pan 101.

In one embodiment, seat protrusion may be configured with a longitudinal length suitable to allow the flexible structure to exert an amount of resistant force when deformed via movement of seat pan 101. The longitudinal length of seat protrusion may be based on, for example, the sleeve length of flanged bushing 209 and/or longitudinal length of protrusion portion 227 of seat plate 207. The flexible structure my provide resilience force to realign the seat protrusion and the base protrusion 219 when the seat protrusion and the base protrusion are not longitudinally aligned between the top end and the bottom end of the flexible structure.

For example, the seat protrusion, such as protrusion portion 227, may have a first longitudinal direction. Base protrusion 219 may have a second longitudinal direction. Movement of seat pan 101 may cause the first longitudinal direction to be not aligned with the second longitudinal direction to deform the flexible structure. The resilience force provided by the deformed flexible structure may allow a user to exercise the user's body by moving (e.g. tilting, rotating etc.) seat pan 101. The seat protrusion and the base protrusion may be separated with a distance inside the flexible structure, e.g. cylindrical spring 211, to allow movements or changes of shaped such as bending of cylindrical spring 211 and/or compressing/stressing of conical spring 217, to provide the resilience force.

Turning now to FIG. 2B, view 200B illustrates a separate cross sectional view as view 200A of FIG. 2A along a different direction crossing the exercise machine (or exerciser), such as device 100 of FIG. 1.

FIG. 3 is an exploded view of an exercise machine assembly according to one embodiment of the present invention as shown in FIG. 1. Note that seat plate 207 may include protrusion portion 227 opposite to the side of seat plate 207 as shown in FIG. 3.

FIGS. 4A-4D show examples of applications for an exercising machine according to one embodiment of the present invention. Turning now to FIG. 4A, a user may hold on to handle bars of an exercise device, such as device 100 of FIG. 1, while making movements on seat pan in a sitting position. The user can slide seat pan back and forth between positions 401, 403 using waist muscles with the upper body of the user remaining stationary. As similarly shown in FIG. 4B, the user can slide seat pan left and right between positions 405, 407.

Turning now to FIG. 4C, the user can rotate or tilt the seat pan around in a wave like manner via waist movement. For example, the seat pan may be rotated in a counter clockwise direction following positions 409, 411, 415 and 415 repeatedly. Alternatively, as shown in FIG. 4D, the user can perform waist rotating movement in a clockwise direction following positions 417, 419, 421 and 423 repeatedly.
